If it’s doom and gloom you’re looking for, then look no further than Sigur Ros’ version of “The Rains of Castamere.”

The tune is a calling card of death on HBO’s “Game of Thrones” and it showed up most recently on Sunday’s episode, “The Lion and the Rose,” which featured the demise of one major player, possibly the series’ most-hated character.

If you missed the installment, you might want to stop reading now.

Though the song might have been King Joffrey’s idea of a cheery number, “The Rains of Castamere” shouldn’t be played at any wedding, unless you’re trying to get your guests to leave.

The Icelandic trio — drummer Orri Pall Dyrason, bass player Georg Holm and singer Jonsi Birgisson — appeared for a brief moment playing their funereal version at the wedding of King Joffrey (Jack Gleeson) and Margaery Tyrell (Natalie Dormer), but were pelted with coins by the impatient king shortly before his death at the hands of a mysterious poisoner.

Regarding their cameo, Holm said in a statement issued Monday that “it was a great experience for us and fun to meet the cast of the show that we have all been following for a long time. The meanest person in television history, King Joffrey, is played by the sweetest guy Jack Gleeson. It was a brilliant ‘hurry up and wait’ time for us and we would do it again in a heartbeat.”

Sigur Ros isn’t the first band to offer a take on “The Rains of Castamere,” though the group boasts about recording “the gloomiest version so far.”

A similarly bleak rendition from New York depressives the National debuted last year, with Season 3’s episode titled “The Rains of Castamere,” which, of course, was also the installment that concluded with the infamous Red Wedding that left the Stark clan decimated.

“The Rains of Castamere” from Sigur Ros is now available for download on iTunes and Amazon, or you can stream the track here:

The song also will be available on the “Game of Thrones” Season 4 soundtrack, which arrives digitally on June 10, and on CD July 1.
